Leadless Pacemaker Implantation in High‐Risk Patients: Real‐World Outcomes From a Multicenter Israeli Registry

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction Transvenous pacemakers are effective but carry significant short‐ and long‐term complications. Leadless pacemakers were developed to overcome these limitations, however, data in high‐risk patients ineligible for transvenous systems remain limited.

Association of Mitral Valve Geometry at CT with Secondary Mitral Regurgitation after Transcatheter Aortic Valve Replacement in Patients with Aortic Regurgitation

open access: yesReviews in Cardiovascular Medicine
Background: The improvement rate and predictors of secondary mitral regurgitation in patients with aortic regurgitation undergoing transcatheter aortic valve replacement (TAVR) remain unclear.

Quadricuspid aortic valve with aortic regurgitation: a rare echocardiographic finding. [PDF]

open access: yes, 2013
We report on a middle-aged woman treated for chronic hepatitis C virus infection with pegylated interferon. Auscultation revealed a diastolic murmur and the peripheral signs of aortic regurgitation.

Internal Jugular Vein as an Alternative Access for Pacemaker Implantation: A Mostly Left IJ Case Series

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Leadless pacemakers traditionally rely on femoral venous access, which may be limited in patients with unfavorable IVC anatomy, prior interventions, or situations where preserving femoral access is preferred. Internal jugular (IJ) access offers an alternative route, but real‐world data on IJ implantation of single‐ and dual‐chamber ...

Pulmonary arterial mechanoreceptors mediate sustained sympathoexcitation during high altitude hypoxia in humans

open access: yesExperimental Physiology, EarlyView.
Abstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.

Pulmonary arterial mechanoreceptors modulate exercise‐induced sympathetic activation in healthy humans during moderate‐intensity hypoxic exercise

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This randomized cross‐over trial (N = 12) addressed the hypothesis that selective reduction of pulmonary arterial pressure (i.e. manipulation of pulmonary arterial mechanoreceptor activation) during hypoxic exercise would reduce sympathetic outflow (muscle sympathetic nerve activity (MSNA)) in healthy humans.

Valvular Heart Disease and Its Association With Death in Advanced Heart Failure

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Valvular heart disease contributes to symptomatic heart failure, but its prevalence and prognostic significance in advanced heart failure is not well understood. Methods This retrospective population‐based cohort study included adult residents

Aortic valve conserving surgery in patients with aortic regurgitation [PDF]

open access: yes, 2014
INTRODUCTION. In the last two decades, the vlave-conserving surgery of regurgitant heart valves has been evolving. The aortic valve-sparing operations have been developing rather over the last decade, despite the clear benefit of mitral valve repair has ...

The influence of metaboreflex activation on pulmonary pressure with combined chemoreflex activation in acute and chronic hypoxia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Activation of both the metaboreflex via post‐exercise circulatory occlusion and the chemoreflex via acute and chronic hypoxia increased pulmonary artery systolic pressure. Coactivation of these reflexes further increased pulmonary artery pressure in an additive manner.
